PBTCA is widely used in the formulation of efficient scale and corrosion inhibitors and is one of the best performing products. It is also an excellent stabilizer for zinc salts. Widely used as a corrosion and scale inhibitor in circulating cooling water systems and oilfield water injection systems, it is particularly suitable for use in combination with zinc salts and copolymers. It can be used in high temperature, high hardness, high alkalinity, and situations that require high concentration ratios. PBTCA can be used as a chelating agent and metal cleaning agent in the washing industry. PBTCA is generally used in combination with other water treatment agents such as zinc salts, copolymers, organic phosphines, and azoles; If used alone, the dosage is 5-15mg/L.

Product Name: H-VAL-TRP-OH INCI Name: DIPEPTIDE-2 Molecular Formula: C16H21N3O3 Molecular Weight: 303.36 Appearance: White powder Purity: 99% CAS Number: 24587-37-9 Standard: Enterprise Standard Supplier: ZhenYiBio Dipeptide-2 is a mixture containing two amino acid molecules. Dipeptide-2 is used as a skin conditioner, moisturizer, and antioxidant in cosmetics. This ingredient can improve ocular edema and is an effective angiotensin converting enzyme (ACE) inhibitor. They can inhibit the conversion of angiotensin I to angiotensin II, thereby improving blood circulation. Mainly used for removing bags under the eyes and smoothing wrinkles.
