In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Criteria for the accuracy of composite pulses in multiple-quantum NMR, published in 1987-02-01, which mentions a compound: 600-05-5, mainly applied to pulse influence multiple quantum NMR; bromopropionic acid NMR, HPLC of Formula: 600-05-5.
The correct use of composite pulses in multiple quantum NMR spectroscopy is described using the conventional sequence for 1-dimensional multiple-quantum filtration. The criteria for correct composite pulse selection which gives improvement in the NMR spectra are given. The effects of choosing the correct composite pulse were demonstrated for 2,3-dibromopropionic acid. The composite pulses of R. Tycko et al. (1985) are effective in compensating for pulse Errors when applied to an arbitrary initial d. operator.
From this literature《Criteria for the accuracy of composite pulses in multiple-quantum NMR》,we know some information about this compound(600-05-5)HPLC of Formula: 600-05-5, but this is not all information, there are many literatures related to this compound(600-05-5).
