Naproxen sodium (NS) is a sodium salt of propionic acid derivative and demonstrates analgesic, anti-pyretic, and anti-inflammatory properties. It exhibits efficiency in being used as an indomethacin in the treatment of acute musculoskeletal disorders. It belongs to the group of nonsteroidal anti-inflammatory drugs (NSAIDS) and acts by inhibiting the activity of both the cyclooxygenase enzymes, COX-1 & COX-2 and further blocking the synthesis of certain prostaglandins. It is administered in the treatment of ankylosing spondylitis, osteoarthritis, rheumatoid disorders, acute gout, mild to moderate pain, tendonitis, bursitis, dysmenorrhea, fever, and migraine headache. Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.

o-Aminoazotoluene (AAT) is a carcinogenic primary amino azo dye.1
o-Aminoazotoluene (AAT) is categorized as a Class 2B carcinogen by the international agency for research on cancer (IARC). This class of azo dyes are widely used as colorants in a variety of products including leather, cosmetics, paper, toys, plastics, pharmaceuticals, textiles, paints, food, leather, etc. Primary aromatic amines (PAAs) are most commonly used as starting compounds in the production of azo dyes and can often migrate into foodstuffs from food packaging materials. AAT finds applications in coloring oils, fats, and waxes.
