4-Ethoxy-3-methylbenzenethiol CAS 1269528-62-2

Description

Compared with other compounds in its class, the molecular weight of 168.26 g/mol gives 4-Ethoxy-3-methylbenzenethiol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-Ethoxy-3-methylbenzenethiol (CAS 1269528-62-2), molecular formula C9H12OS and molecular weight 168.26 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system, 4-Ethoxy-3-methylbenzenethiol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 168.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 4-Ethoxy-3-methylbenzenethiol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
