FAQ - Technical & Supply Chain
-
Q:
Is CAS 104-88-1 the correct registry number for 4-Chlorobenzaldehyde?
A: Yes, CAS 104-88-1 specifically identifies the para-isomer (4-Chlorobenzaldehyde), distinguishing it from the ortho- (2-) or meta- (3-) chlorobenzaldehyde isomers. -
Q:
Why is 4‑chlorobenzaldehyde commonly used as a pharmaceutical intermediate?
A: 4‑Chlorobenzaldehyde provides a para‑substituted aromatic aldehyde structure that is well suited for condensation and derivatization reactions, making it a practical intermediate in the synthesis of pharmaceutical and fine chemical compounds.
