How does CAS 89-98-5 differ from its para-isomer in industrial use?

CAS 89-98-5 refers specifically to the ortho-isomer, where the steric hindrance and electronic effects of the chlorine atom at the 2-position dictate different reaction kinetics and end-product properties compared to p-chlorobenzaldehyde (CAS 120-17-2), particularly in the synthesis of specific pharmaceutical drugs.

Is o‑chlorobenzaldehyde supplied as an intermediate rather than a finished product?

It is typically supplied as a chemical intermediate intended for controlled organic synthesis and further processing, not as a finished consumer product.

o‑Chlorobenzaldehyde CAS 89-98-5

o‑Chlorobenzaldehyde, also referred to as 2‑chlorobenzaldehyde and abbreviated as OCBA, is an aromatic aldehyde containing an ortho‑chloro substituent, corresponding to CAS 89-98-5. It serves as a reactive chemical intermediate in organic intermediate synthesis, where its aldehyde functionality enables condensation, cyclization, and substitution reactions for the preparation of downstream fine chemical and specialty intermediates. The material is supplied for industrial use with competitive factory pricing, customized specifications, and complete documentation including MSDS, TDS, COA, supporting bulk supply.
