4-Chlorobenzaldehyde
4-Chlorobenzaldehyde (p-chlorobenzaldehyde; CAS 104-88-1; EC 203-247-4) is a high-purity aromatic aldehyde (C₇H₅ClO, molecular weight 140.57 g/mol, melting point 46–48 °C, boiling point ≈213.5 °C) supplied by Royalchem Spain at ≥99% purity. Its reactive aldehyde group on a para-chlorinated benzene ring makes it a key building block for the fungicide tebuconazole, the plant-growth regulator uniconazole, and the insecticide chlorfenapyr, as well as for the muscle relaxant chlormezanone, triarylmethane dyes (such as Acid Brilliant Blue), stilbene optical brighteners, and a range of specialty fine chemicals made by aldol and Knoevenagel condensations.
Product Description
4-Chlorobenzaldehyde
High-Purity Aromatic Aldehyde (p-Chlorobenzaldehyde) — Tebuconazole & Agrochemical, Pharmaceutical, Dye and Optical-Brightener Intermediate
CAS: 104-88-1 EC: 203-247-4 Assay: ≥ 99%
4-Chlorobenzaldehyde (p-chlorobenzaldehyde, CAS 104-88-1) is a high-purity aromatic aldehyde and a versatile intermediate for agrochemical, pharmaceutical, dye, and fine-chemical synthesis. Its reactive aldehyde group on a para-chlorinated benzene ring makes it a key building block for the fungicide tebuconazole, the plant-growth regulator uniconazole, and the insecticide chlorfenapyr, as well as for triarylmethane dyes, optical brighteners, and specialty chemicals. A low-melting white solid, it is supplied by Royalchem Spain at ≥ 99% purity, delivered from our Valladolid distribution hub by bag or drum with COA and SDS for every batch.

*Regulatory: EINECS-listed (EC 203-247-4); supplied in line with EU REACH requirements; manufactured under ISO 9001. GHS — Warning: harmful if swallowed (H302); causes skin and serious eye irritation (H315, H319); may cause respiratory irritation (H335); some classifications also assign skin sensitisation (H317) and toxicity to aquatic life with long-lasting effects (H411) — avoid release to waterways. Generally not a transport-regulated dangerous good — confirm against the current SDS. As an aldehyde it slowly air-oxidises to 4-chlorobenzoic acid; keep containers sealed. Always refer to the current SDS.

Main Applications
Agrochemical Intermediate
A key building block for the triazole fungicide tebuconazole, the plant-growth regulator uniconazole, and the insecticide chlorfenapyr, as well as other crop-protection actives built from the para-chlorophenyl group.
Pharmaceutical Intermediate
A reactive aldehyde used in API synthesis — for example the muscle relaxant chlormezanone — via condensation, reductive amination, and related routes to substituted benzyl and benzylidene derivatives.
Dyes, Optical Brighteners & Fine Chemicals
An intermediate for triarylmethane dyes (such as Acid Brilliant Blue), stilbene-type optical brighteners, and a wide range of specialty fine chemicals made by aldol and Knoevenagel condensations.
Logistics & Packaging
Standard Packaging:
200 kg fiber or HDPE drums, or 25 kg bags — or to customer requirement. Distributed by Royalchem Spain from our Valladolid hub. Shelf life 24 months in original sealed packaging.
Storage Conditions:
Store in a cool, dry, well-ventilated area, away from heat, direct light, and strong oxidising agents, with containers tightly closed. The low melting point (≈ 47 °C) means it can soften in warm conditions; as an aldehyde it slowly air-oxidises to 4-chlorobenzoic acid, so keep sealed and consider nitrogen blanketing.
