If your next step needs 4-chlorobenzonitrile (CAS 623-03-0), you're likely comparing suppliers on three things: consistency, documentation, and delivery.
Buyers looking for a reliable 4-chlorobenzonitrile supplier or p-chlorobenzonitrile manufacturer usually want something simple — product in stock, clear specs, and no delays on paperwork.
Snowhite Chemical Co., Ltd. supplies this intermediate to pharma, agrochemical, and dye manufacturers worldwide, with stable batches and export-ready support.
1. Product Basics
4-Chlorobenzonitrile — also known as p-chlorobenzonitrile, p-cyanochlorobenzene, or PCBN — is an aromatic nitrile (C₇H₄ClN, ).
It is typically supplied as white to off-white crystalline powder or flakes, with a melting range commonly reported around 90–95 °C.
It has low solubility in water and is typically soluble in organic solvents such as alcohols and chlorinated solvents.
From a synthesis standpoint, the nitrile group is the key functional site. It can be converted into different intermediates depending on your route — for example, acid derivatives or amine derivatives — which is why PCBN is widely used in multi-step synthesis projects.
