Pharma Intermediates & Building Blocks for United States

The pharma intermediates division connects API developers with India's deep base of fine-chemical manufacturers. The range includes key starting materials (KSMs), advanced intermediates for established APIs, heterocyclic building blocks such as pyridines, pyrimidines, indoles and piperazines, protected amino acids, boronic acids, chiral synthons and coupling reagents.

Supply runs from gram-scale building blocks for medicinal chemistry to kilo and multi-tonne quantities for commercial API routes. Specifications cover assay, related substances, residual solvents and, where required, enantiomeric purity or genotoxic impurity limits. Every batch ships with a COA and a GHS SDS, and route or change-control information can be discussed where the manufacturer is able to share it.

API manufacturers, CDMOs, discovery chemistry groups and agrochemical companies that share similar chemistry are typical customers. Many buyers use Indian intermediates to diversify supply chains or reduce landed cost, so we focus on consistent specifications across batches, realistic lead times and clear packaging and dangerous-goods documentation for export. Samples can usually be arranged ahead of scale-up so that buyers can run use-tests and impurity-fate studies before committing to volume. Where a molecule has several possible sources, we explain the differences in specification and documentation so buyers can choose knowingly.

Compliance in United States

Regulator: FDA (CDER)

Chemical substances imported into the US must comply with the Toxic Substances Control Act, and the importer files a TSCA positive or negative certification at entry. Substances must be on the TSCA Inventory or exempt. APIs for human drugs are FDA-regulated, typically supported by a Drug Master File and cGMP manufacturing, and are subject to FDA entry review (FSVP applies to food, not chemicals). List I and List II chemicals require DEA import registration and declarations, and ocean shipments need an ISF 10+2 filing with CBP before loading.
