Top Chlorobutanol Anhydrous Manufacturers and Suppliers in India (2026 Guide)

27-07-2026

Introduction

India has a deep and established manufacturing base for pharmaceutical preservative excipients, and chlorobutanol, in both its anhydrous and hemihydrate forms, is no exception. Numerous manufacturers and traders across Gujarat, Maharashtra, and other pharmaceutical manufacturing hubs supply chlorobutanol to domestic formulators and international buyers. This guide explains how the Indian supplier landscape for chlorobutanol is structured, what to check before placing an order, and how to avoid common sourcing mistakes.

The Indian Chlorobutanol Supply Landscape

Chlorobutanol suppliers in India generally fall into a few broad categories:

Established specialty chemical and excipient manufacturers, some with decades of operating history and direct GMP certified manufacturing facilities, often supplying under IP, BP, EP, USP, NF, and JP standards with full regulatory documentation including DMF and Written Confirmation
Trading and export focused companies, based heavily out of Ahmedabad, Gujarat, that source from various manufacturers and offer chlorobutanol anhydrous and hemihydrate for both domestic sale and export
B2B marketplaces and directories, such as IndiaMART, TradeIndia, and PharmaCompass, which list multiple suppliers with pricing, minimum order quantities, and contact details, though the underlying manufacturing quality and documentation still needs to be verified directly with each listed company
Sourcing platforms with instant quoting, such as Clyzo, which aggregate multiple chlorobutanol suppliers in one place with product level detail and a structured quote request process

What to Check Before Ordering Chlorobutanol Anhydrous

Given how many suppliers list chlorobutanol under slightly different descriptions, the following checks help confirm you are getting the correct grade for your formulation:

1. Confirm the exact form (anhydrous vs hemihydrate)

Some listings use "chlorobutanol" generically without clearly specifying the form. Always confirm in writing, ideally via the certificate of analysis, that the product is genuinely the anhydrous grade if that is what your formulation requires, since the two forms differ in melting point and water content.

2. Request a current certificate of analysis

A legitimate supplier should provide a batch specific certificate of analysis showing assay percentage, related substances, water content, and any other pharmacopeial test parameters, not just a generic specification sheet.

3. Verify pharmacopeial compliance for your target market

Confirm whether the material is tested against USP, NF, EP, BP, IP, or JP standards, and make sure this matches the regulatory filing requirements for the market where your finished product will be sold.

4. Ask about regulatory documentation for export

If you are exporting your finished formulation, ask whether the supplier can provide a Drug Master File (DMF) reference, Written Confirmation (WC), or other documentation required by your target market's regulatory authority.

5. Check quality certifications Look for ISO 9001, WHO-GMP, cGMP, or equivalent quality system certifications, along with any additional certifications relevant to your market, such as Kosher or Halal status if relevant to your product positioning.

6. Confirm minimum order quantity and packaging options

Chlorobutanol suppliers in India often list a range of pack sizes, from small laboratory trial quantities to bulk commercial volumes. Confirm the supplier can support both your current order size and future scale up needs without requiring a change of source.

7. Review pricing in context, not in isolation

Prices for chlorobutanol can vary meaningfully between suppliers based on form, grade, documentation level, and order quantity. A lower quoted price without verified documentation is not necessarily a better deal once regulatory risk is factored in.

Common Red Flags to Watch For

Listings that do not specify anhydrous versus hemihydrate clearly
Suppliers unwilling to provide a batch specific certificate of analysis before order confirmation
Pricing significantly below market average with no explanation, which can sometimes indicate lower grade, non-pharmacopeial material
No verifiable regulatory filings (DMF, CEP, or WC) for suppliers claiming export capability to regulated markets

Why Centralized Sourcing Platforms Are Gaining Traction

Because chlorobutanol is offered by many small and mid sized suppliers across India, each with their own documentation practices and communication channels, manufacturers increasingly prefer sourcing platforms that consolidate multiple verified suppliers in one place. This reduces the time spent chasing individual quotes and documentation requests across scattered trade directory listings, and makes it easier to directly compare pack sizes, supplier ratings, and product specifications side by side. Clyzo, for example, lists chlorobutanol excipient from multiple suppliers with instant quote generation, which can shorten the sourcing cycle for formulators evaluating several options at once.

Common Questions About Sourcing Chlorobutanol in India

Is chlorobutanol anhydrous readily available from Indian manufacturers?

Yes, several established Indian manufacturers and traders offer both anhydrous and hemihydrate chlorobutanol, often under IP, BP, EP, USP, NF, and JP standards.

Do I need an import license to buy chlorobutanol from an Indian supplier?

Regulatory and import requirements depend on your country's specific pharmaceutical raw material import regulations, so this should be confirmed with your own regulatory affairs team or customs consultant rather than assumed from the supplier side alone.

How do I confirm a supplier's chlorobutanol is genuinely pharmacopeial grade?

Request a current, batch specific certificate of analysis showing test results against the specific pharmacopeial monograph you require, and cross check this against the supplier's stated regulatory filings such as a DMF number.

What is a reasonable minimum order quantity for chlorobutanol from Indian suppliers?

This varies significantly by supplier, ranging from small kilogram scale quantities suitable for lab trials up to bulk commercial volumes, so confirm minimum order quantity directly during the quoting process.

Conclusion

India offers a strong and varied supplier base for chlorobutanol anhydrous and hemihydrate, but the range of listings across trade directories means buyers need to verify form, grade, and documentation directly rather than relying on a generic product description. Prioritizing suppliers with verifiable regulatory filings, batch specific certificates of analysis, and transparent quality certifications will reduce sourcing risk significantly compared to selecting purely on listed price.
