The formula is C 15 H 27 N 3 O and the CAS Registry Number is 90-72-2. It is REACH registered and the European Community Number is 202-013-9. [2] [3] [4] Uses.
pH indicators: a graphic view. A pH indicator is a halochromic chemical compound added in small amounts to a solution so the pH (acidity or basicity) of the solution can be determined visually or spectroscopically by changes in absorption and/or emission properties. [1]
17-4 stainless steel can be heat treated to approximately 44 Rc, [1] and an ultimate tensile strength of 1,300 MPa (190,000 psi). Its density ranges from 7,800 to 7,900 kg/m 3 (0.282 to 0.284 lb/cu in), and its modulus of elasticity ranges from 197 to 207 GPa (28.5 × 10 ^ 6 to 30.0 × 10 ^ 6 psi).

Phenyl isothiocyanate (PITC) is a reagent used in reversed phase HPLC.PITC is less sensitive than o-phthaldehyde (OPA) and cannot be fully automated. PITC can be used for analysing secondary amines, unlike OPA.
In chemistry, pH (/ p iː ˈ eɪ tʃ / pee-AYCH), also referred to as acidity or basicity, historically denotes "potential of hydrogen" (or "power of hydrogen"). [1] It is a logarithmic scale used to specify the acidity or basicity of aqueous solutions.
Tumor-associated glycoprotein 72 (TAG-72) is a glycoprotein found on the surface of many cancer cells, including ovary, [1] [2] [3] breast, colon, [4] lung, and pancreatic cancers. [ 5 ] [ 6 ] It is a mucin -like molecule with a molar mass of over 1000 kDa .
Perchloric acid forms an azeotrope with water, consisting of about 72.5% perchloric acid. This form of the acid is stable indefinitely and is commercially available. Such solutions are hygroscopic. Thus, if left open to the air, concentrated perchloric acid dilutes itself by absorbing water from the air.
