Q1: What is Appolo-425 and what is its CAS number?
A1: Appolo-425 is a phenylamino-triazine UV absorber (CAS 1248-66-4, C23H16N4O2, mol. wt. 356.38) for textile auxiliary applications. It appears as an off-white to light yellow powder with a high melting point of 240–243°C and HPLC purity NLT 98.5%.
Q2: How does Appolo-425 differ from typical hydroxyphenyl triazine (HPT) UV absorbers?
A2: Unlike standard HPT UV absorbers that have an alkoxy or aryloxy substituent on the triazine ring, Appolo-425 features a phenylamino (–NHPh) group at the 6-position of the s-triazine ring, giving it a different absorption profile and suitability for specific textile dyeing and auxiliary processes.
Q3: What are the key quality parameters for Appolo-425?
A3: It meets purity by HPLC of NLT 98.5%, loss on drying NMT 0.50%, transmittance at 460 nm NLT 75.0%, and transmittance at 500 nm NLT 85.0%, with a solubility specification of clear solution at 2% in DMF.
Q4: On which global regulatory inventories is Appolo-425 listed?
A4: It is listed on China IECSC and Korea KECL, but is not currently listed on major Western inventories such as US TSCA, EC Inventory, Canadian DSL, or Japan ENCS — buyers exporting finished goods to those markets should verify compliance requirements.
Q5: Where is Appolo-425 manufactured and can it be sourced directly from the manufacturer for export?
A5: Appolo-425 is manufactured by Sarex in India at 200 MT annual capacity. As a leading fine chemical manufacturer and exporter, Sarex supplies it directly to textile chemical producers and formulators in more than 40 countries.
