Pigment Yellow 34DISCONTINUED(CAS: 1344-37-2)

Pigment Yellow 34 (CAS: 1344-37-2) is a stable, light-fast, and air-sensitive synthetic organic pigment. It has a molecular weight of approximately 1,458 g/mol and is moderately soluble in organic solvents. It shows low reactivity with most organic compounds but is susceptible to oxidation and hydrolysis under certain conditions.

Pigment Yellow 34 (CAS: 1344-37-2) is synthesized through a condensation reaction involving a naphthol derivative and a ketone, typically using a sulfuric acid catalyst. The process yields a high molecular weight polymer which is then precipitated and purified to obtain the pigment. This method ensures a high selectivity and yield, with the final product being a stable, yellow-colored pigment.

Pigment Yellow 34 (CAS: 1344-37-2) is widely used in the printing ink, paint, and plastic industries. It is also employed in coatings, adhesives, and as a colorant in textile manufacturing. Additionally, it is used in some pharmaceutical formulations and pigments for polymers and plastics.

When handling Pigment Yellow 34 (CAS: 1344-37-2), ensure that appropriate personal protective equipment (PPE) is worn, including gloves, goggles, and a lab coat. Work in a well-ventilated area or a fume hood to avoid inhalation. Store the pigment in a cool, dry place, away from direct sunlight. In the event of a spill, immediately clean up using appropriate absorbent materials and dispose of according to local regulations. Always refer to the Safety Data Sheet (SDS) for detailed handling instructions and emergency procedures.
